发布时间：2018-10-23 15:31
【摘要】：目的了解南京市肾综合征出血热(HFRS)流行病学特征,为制定有效的防控策略和措施提供科学依据。方法采用描述流行病学方法,分析2011-2016年南京市报告的HFRS病例流行特征,以及病例临床特征和可疑暴露信息等。结果 2011-2016年南京市共报告HFRS确诊病例194例,年均32例(19~45例),年均报告发病率为0.39/10万(0.23/10万~0.55/10万)。季节上呈现双峰分布,春季(3~6月)峰值高于冬季峰(12月~次年1月)。男性多于女性,病例年龄中位数为48岁(12~82岁),农民占57%。高淳区报告病例数占全市的45%(87/194),年均报告发病率为3.4/10万(1.9/10万~4.8/10万)。发病存在空间正相关(Moran's I=0.17,P0.05),高淳区(2012年4月1日-2015年3月31日)和江宁区(2013年1月1日-2013年5月31日)存在时空聚集。病例多具有发热、"三痛","三红"等较典型症状或体征,但有明确暴露史者比例极低。结论南京市HFRS发病平稳,应根据流行特征在重点地区和人群开展综合防控措施。
[Abstract]:Objective to investigate the epidemiological characteristics of hemorrhagic fever with renal syndrome (HFRS) in Nanjing and provide scientific basis for effective prevention and control strategy. Methods descriptive epidemiology was used to analyze the epidemiological characteristics of HFRS cases reported in Nanjing from 2011 to 2016, as well as the clinical characteristics and suspicious exposure information. Results A total of 194 HFRS cases were reported in Nanjing from 2011 to 2016, with an annual average of 32 cases (1945 cases) and an annual reported incidence rate of 0.39 / 100 000 (0.23 / 100 000 ~ 0.55 / 100 000). The peak value in spring (from March to June) is higher than that in winter (December to January of next year). The median age of the cases was 48 years (1282 years), with farmers accounting for 57%. The reported cases in Gaochun accounted for 45% (87 / 194) of the city, with an average annual reported incidence of 3.4 / 100 thousand (19.9 / 100,000-4.8 / 100,000). There was a positive spatial correlation (Moran's), a spatiotemporal aggregation in Gaochun (from April 1, 2012 to March 31, 2015) and Jiangning District (from January 1, 2013 to May 31, 2013). Most of the cases had fever, three pain, three red and other typical symptoms or signs, but the proportion of patients with definite exposure history was very low. Conclusion the incidence of HFRS in Nanjing is stable, and comprehensive prevention and control measures should be carried out in key areas and populations according to epidemic characteristics.
